“Dittos on canned food. If you’re not worried about it freezing it’s definitely the cheapest.”
Dumb question, probably, but freezing ruins canned foods?
Canned foods often contain a lot of water. Freezing water expands, damaging the can. Have you never seen a frozen can of soda with the top and bottom bulging out?
Yes. The water in it will expand and rupture the can.
